Specification of Letters Patent.

Application filed March 31, 1909. Serial No. 487,061.

To all whom it may concern: r

Be it known that I, CHARLES F. 'Jr., citizen of the United States, Cleveland, in the county of Cuyalioga and State of Ohio, have invented certain new and useful Im rovements in Projection-Lantern- Slide-Ho tiers, of which the following is a specification.

My invention relates to a new and useful improvement in projection lantern slide ho ders, all substantially as shown and described and particularly pointed out in the claims.

. In the accompanying drawings, Figure 1 is a sectional elevation of a lantern showing my improved holder in cross section therein, and Fig. 2 is a perspective view of the holder with one of the hinged slide suv ports or shutters down to 'show the inner side.

The novelty in the foregoing views lies mainly in the novel and. orlginal means. for displaying both ordinary glass slides and 'DUT'roN, residlng at opaque or dark slides, like'post-cards, in the same holder, with lightsdifierently disposed as to bothto get. the desired effects as will hereinafter appear. s

In Fig. 1 L represents the'laiitern as an entire embodiment and H the slide holder ada ted to be slidably mounted therein, as

in therespective halves or portions thereof into focus alternately, whether the usual slides .or post cards or the like be employed for display. Now, in this alternative use or ada tation of the holder that the invention resi es, and toy this end the said holder has a rectangular 0 ening in each half and a slide support or s lutter D hinged atthe bottom of each opening adapted to close said opening. The said shutters or doors are hinged to swing down in order to render both sides thereof equally available for using either kind of slide therewith, and each shutter or 'door is provided 4.; on one side with parallel angle iron or equivalently shaped retaining ides 2 for the glass slides, and substantia 1y similar guides 1 3-on its other or front side for the post-cards.

As to these latter guides while guided is shown across the upper porport the card so as to bring the slides 1 it is more particularly or supports, however, they are shown spaced apart ,far enoughto receive a card lengthwise between them,

tion of the shutter adapted to receive the card endwise and rests 5 at the bottom supwhen thus inserted. This affords accommodation for cards with pictures in either position thereon. Obviously these means for engaging both the glass slides and the cards may be of any kind that Will confine the same removably in the holder.

I have referred to post-cards particularly, but offcourse any other card bearing a pic- Patented Mar. IHIU.

ture or designs which may be thrown upon a screen can be used if it be of'the right size. These cards are opaque and will not show the light through as glass slides do, and hence I require a lamp 6 for the glass slides located at the rear thereof, and a lamp or lamps 7 located in front of the holder for 0 aque cards, the pictures in this latter case eing reflected on the screen.

It should have been stated thateach shutter or door D has a central opening 8 through which the glass slide shows, but which is of no service if cards be shown because they cover the same'over at the front. Only one set of lamps is used at a time according as a lass slide or a card slide is displayed.

%The lantern shell or casing has a chamber C ada ted to receive the holder H and lamp 6 is esigned to be used exclusively with glass or translucent slides, while lamp 7 is esigned to be used excluslvely with opaque or card slides.

What I claim is:

1. In projection lanterns, a slide holder adapted to support glass slides onone side thereof and card slides on the other side.

2. slide holder for projection lanterns provided with separate means for supporting glass and opaque slides respective y..

r 3.; A projection lantern and a slide holder therein having a hinged door with a central opening and constructed on one side to support atranslucent slide and an opaque sli e on the outer, and a separate lamp for each of said slides disposed beforeand behind said,

holder respectlvely. q a
